Storing information about requested/failed/successful scene requests would allow the program to be used similarly to landsatlinks/FORCE's download suite.

Additionally, it may be possible to implement a background task which checks for availability while other threads already query the database for downloadable products.

Using the sqlite3 module from the standard library should suffice and not introduce additional dependencies

[ ] Check implementation proposal in standalone script
[ ] Assess storage space usage by database for multiple scenes when storing all metadata
[ ] Write at least some tests for the class method
[ ] integrate into cli_funcs::download

Different satellites have different metadata, so if all is to be stored, there would need to be a case distinction. The easier and probably better approach would be to select a subset of attributes
